Do you know why pumpkins have orange coloring? We can tell you the reason for that. Most pumpkins contain organic pigments called carotenoids that give their flesh and skin the classic deep orange tint. But what is more interesting, not all pumpkins turn orange like in our Pumpkin Gradient cursor pack - some of them are selectively bred to be white, red, or even blue. We bet you had no idea about that. An unripe regular pumpkin, a giant pumpkin begins life with a bright yellow color. As it grows, it gradually turns a pale yellow and then - some shade of orange.
